Abstract
We studied the secondary relaxation in galactose‐water mixtures by analyzing the dielectric loss spectra with two different fitting methods. The first method was the free fit without any constraint and the second method was the fit with the coupling relation in coupling model (CM) [1, 2, 3]. The behavior of the secondary relaxation process were very similar to that of the secondary relaxation process with changing the rotational‐traslational (RT) coupling constant in the schematic mode coupling theory (MCT) [4, 5]. The secondary relaxation times (τJG) obtained by the constrained fit contain a large uncertainty and were consistent with τsec within the experimental errors. We also found that the fitting quality of free fit was better.
